Course Overview

This course teaches bit manipulation, a powerful technique to enhance algorithmic and problem-solving skills. It is a critical topic for those preparing for coding interviews for top tech companies, startups and industry leaders. Competitive programmers can take full advantage of this course by running most of the bit-related problems in O(1) complexity. The course will begin by educating you about the number system and its representation, decimal and binary, followed by the six bitwise operators: AND, OR,...Show More
